Abstract: 356,121. Filling and closing bottles. OGDEN, J., of Mauri Bros. & Thomson, Ltd., Bourke Street, Waterloo, near Sydney, Australia. Feb. 25, 1930, No. 6224. Convention date, Feb. 26, 1929. Void [Published under Sect. 91 of the Acts]. [Class 125 (ii).] In machines for syruping, filling or crowning bottles, the bottle is brought into contact with the respective mechanism or mechanisms by fluid operated mechanism. A rotating receiver 15, Fig. 1, for the operating fluid is supported by a fixed base 12 and carries a number of filling blocks 16 adapted to raise bottles to filling heads 17 after they have received a supply of syrup from a syruping head 20, the bottles meanwhile resting on a table 24 supported by two pillars 18, 19, the former of which carries the syruper and the latter the crowning mechanism. A bottle placed by hand beneath the syruping head is centred beneath it by arms 99 on a transfer mechanism 25 comprising a housing 97, Fig. 10, intermittently rotated by a cam wheel 69 engaged by a cam 70, Fig. 5, on the receiver 15, each pair of arms 99 being mounted on a pivot 98 about which the arms are rotated in opposite directions by pinions 100 engaged by teeth on a segment 101 which is mounted on a spindle 102 carrying a cam 103 engaging a track 104 on a fixed plate 105. The segment 101 is mounted eccentrically on the spindle 102 to make one arm move more rapidly than the other. Alternatively, the transfer mechanism may comprise a pair of arms on a spindle formed with a spiral groove adapted to be engaged by a pin on a reciprocating sleeve member. Syruping mechanism.-The syruping head comprises a cylinder 41, Fig. 3, integral with a supporting bracket 42, and containing a piston 43 carried by a hollow piston rod 44. Ducts 110, 111 connect opposite sides of the piston to the receiver 15 and, the area exposed above the piston being greater than that below it, admission of pressure fluid through the duct 110 drives down the piston against the action of the fluid on its underside which is permanently in connection, with the receiver 15. The hollow piston rod communicates by an extension 45 with the syrup reservoir 22 and through a valve 53 with a chamber 48 secured to its lower end. The chamber 48 communicates through a non-return valve 51 in a piston 47 with a mouthpiece for the bottle and is thrust downwards by springs 52. Downward movement of the piston 43 causes the piston 47 to rise in the chamber 48 and expel syrup into the bottle. When the pressure is relieved, the pressure on the underside of the piston 43 raises it and draws a fresh charge of syrup into the chamber 48. An adjustable nut 50 limits the entrance of the piston 47 into the chamber 48 and determines the charge of syrup delivered. A gravity-actuated syruper may replace the hydraulic one and comprise a chamber normally in communication with the syrup reservoir but cut off therefrom when in communication with the bottle. Filling mechanism. The bottle blocks 16 each comprise a piston 56 and wide rod 57 supporting a bottle rest 58 and raised when a double headed valve 60 is thrust outwardly in its valve chamber 59 by a fixed cam on the machine, pressure fluid then entering by a duct 63 and overcoming the constant pressure applied through a duct 62 to the top of the piston 56. When the filling operation is completed, another cam thrusts the valve 60 inwards cutting off the duct 63 and allowing fluid from the cylinder to run down to a sump through ducts 64, 65. The transfer mechanism removes the filled bottle to the crowning head. Crowning mechanism. The rod 19, is screwed to receive the crowning head 76, Fig. 4, which includes a cylinder 75 and piston 77 having a hollow stem 78,in which a spring-pressed crowning plunger 79 is mounted. Pressure fluid admitted through a conduit 81 drives down the piston against constant pressure on its underside by fluid supplied through a conduit 82 and this latter pressure raises the piston and crowning plunger when the top pressure is released.
